Definitions

  • Cartridge cases of light metal are liable to fasten in the cartridge chamber of the firearm, partly due to the fact that the material has insuliicient elasticity so that the cartridge cases are expanded permanently by the shot and thereby are jammed tight in the cartridge chamber, partly because light metal under heat influence has a very strong adhesion to steel.
  • These circumstances in connection with the insuiicient strength of the material can give rise to tearing off of the cartridge flange, which is one of the most time-consuming function faults in automatic firearms.
  • Cartridge cases have also been made of so called plastics, for instance synthetic resin materials, however with a bottom piece of brass or similar relatively strong material.
  • plastics cartridge cases When such plastics cartridge cases are employed for live cartridges the relatively high forceful generation of heat caused by firing such cartridges will bring the cartridge chamber up to such temperature that the cartridge cases are liable to soften or melt when inserted into the chamber, which gives rise to the function faults called tear-offs or jammers.
  • cartridge cases with a wall comprising two layers, the outer layer being made of synthetic resin material, and the inner layer being made of light metal, for instance aluminium.
  • the object of providing an aluminium case with an outer coating of plastics is to prevent the aluminium vnom adhering to the wall of the cartridge chamber.
  • this cartridge case has the same drawback as mentioned above in connection with the plastic cartridge cases, i.e. that the plastic material softens or melts when the cartridge is inserted in the cartridge chamber, if the firearm has be-y come hot by shooting.
  • the invention relates to a cartridge case which comprises two sleeve members which are open at the rear end, the one being arranged co-axially in the other, the rear end of they outer sleeve member being attached to a tubular extension of a bottom piece of a suitable material, and the cartridge case according to the invention is characterised in that the external sleeve member is made of light metal and the internal sleeve member is made of artificial resin material or similar material.
  • FIGURE 1 is an axial sectional view of a cartridge case of a first embodiment
  • FIGURE 2 an axial sectional view of a cartridge case of a second embodiment
  • FIGURE 3 an axial sectional view of a cartridge case of athird embodiment
  • FIGURE 4 an axial sectional View of a cartridge case of a fourth embodiment
  • FIGURE 5 an axial sectional view of a cartridge case of a fifth embodiment.
  • FIGURE 1 a cartridge case comprising an outer sleeve member 1 of light metal and an inner sleeve member 2 of artificial resin material or material of similai properties, and a bottom piece 3.
  • the rear end of the outer sleeve member is shrinked on atubular extension 4 of the bottom piece 3.
  • the light metal sleeve member 1 encloses tightly the resin sleeve member 2.
  • the rear portion of the inner sleeve member is arranged outside the extension 4, and in the extension is arranged a tightly fitting plastic cup.
  • the sleeve member 2 is closed at its rearl end by an end wall which is very thin, at least at its centre, toprovide for easy penetration of ignition sparks passing from an ignition chamber in the rear side of the bottom piece through a bore in said bottom piece.
  • the rear portion of the outer sleeve 1 encloses tightly the extension 4.
  • Each sleeve member 1 and 2 comprises a front extension providing a hollow portion, 5 and 6 respectively, the outer shape of such portion being substantially as the shape projectile or bullet.
  • the extension 5 of the light metal sleeve 1 is closed at the front end and is, in a manner known per se, provided with at least two weakening lines or grooves which cross each other.
  • the extension 6 ⁇ of the resin sleeve member '2 is open at its front end.
  • The'cartridge case is iilled with powder (not shown) in the usual manner.
  • the cartridge case shown in FIGURE 3 is also for a ank cartridge.
  • the resin sleeve member 2 has no :tension 6.
  • FIGURE 4 shows a bottom piece 3 with a tubular ex- :nsion 4 having a relatively thick wall.
  • the rear end f the inner sleeve member 2 has a stepped configuration nd extends into an annular internal recess in said tubutr extension 4, the rear end face of the sleeve member 2 ngaging a shoulder 14 on the extension 4.
  • the rear nd portion of the inner sleeve member 2 provides a as trap.
  • the rear end portion of the outer sleeve mem- ⁇ er 1 is rolled into two circumferential grooves 8 in the fottom piece 3 and its extension 4.
  • the inner sleeve nember 2 has no extension 6.
  • FIGURE 5 a cartridge case in which the esin sleeve member 2 has a very heavy wall.
  • the rear nd portion of the sleeve member 2 is recessed and a 'earwardly protruding end portion thereof projects into in annular recess in the tubular extension 4 of the botvom piece 3.
  • An internal shoulder on the sleeve member E engages a shoulder 14 on the extension 4.
  • a hollow metal nember 81 provides a bullet-shaped end portion and has ,ts rear engaging the inner side of a narrow front portion :if the outer sleeve 1 and the front end of the internal sleeve 2.
  • the invention is not limited to the embodiments shown and described.
  • the cartridge case can also be adapted for use in live cartridges. This is true as regards to the embodiments of FIGURES 1 through 5 provided that the bullet-shaped hollow end portion is replaced by a bullet.
  • a cartridge case comprising a bottom piece having a substantially tubular extension and formed with an axial bore in its bottom, a light metal sleeve forming an outer shell and surrounding said tubular extension so as to constitute a tight it therewith, and an inner sleeve made of plastic and constituting a lining in said outer shell and extending into said tubular extension to also constitute a lining in the latter, said inner sleeve being closed at the end engaging said bottom piece by means of a bottom integral with said inner sleeve and weakened at a place opposite said axial bore in said bottom piece.
  • a cartridge case comprising a bottom piece having a substantially tubular extension, an inner annular shoulder in said tubular extension, a substantially cylindrical groove formed in said annular shoulder, a light metal sleeve forming an outer shell and surrounding said tubular extension so as to constitute a tight fit therewith, and an inner sleeve of plastic material lining said outer shell and extending into said tubular extension to abut against said annular shoulder, said inner sleeve having at its ends abutting against said annular shoulder a substantially cylindrical ange extending into said cylindrical groove.
